Question

我将使用Jython导入两个据称相同的java文件进行比较。比较是在返回值，签名和构造函数的基础上进行的（这很好，但问题在于导入）。一个文件位于submission文件夹中，另一个文件位于solution文件夹中。问题如下，

当我运行以下代码时，

    sys.path.append('Solution/')
    import GeometricShape
    sys.path.pop()

    sys.path.append('Submission/')
    import GeometricShape    <---- the imported module is the same as the one above
    sys.path.pop()

第二个导入的GeometricShape是solution文件夹中的一个，而它应该是submission文件夹。按del(sys.modules["GeometricShape"])删除模块仍会以某种方式将第一个GeometricShape保留在内存中。 imp.load_source不起作用，因为它不是python源文件。在目录中创建__init__并将模块导入from Solution import GeometricShapes不起作用，因为我收到以下错误，

有解决方法吗？
